ImageMagick’s identify should be able to identify any files you have enabled while compiling it. For example,

identify ceaec3da6ef432af59fbdad2c93c277e.jpg
ceaec3da6ef432af59fbdad2c93c277e.jpg JPEG 160×90 160×90+0+0 DirectClass 8-bit 10.1797kb

Nice. This is a perfect example of the power of the Linux shell. It may look comlicated, but after you get over the learning curve, you can do things that are incredibly powerful.

Thanks for the example,

Daniel

wow…
You should put it into the convert command (imagemagick) to scale it if it’s bigger

Dennis,

I’m not actually sure, but I think you’d have to find a utility that could check the dimensions of a jpg image, and you could substitute it on the command line.

Alternatively you could probably write a php, python or perl script and interface with the gd library.

Victor,

I certainly wouldn’t advocate this type of thing for “normal” people =)

Damn those commands look complicated,

And then people wonder why linux is so unpopular with the *normal* people…

Just my 2 cents.
